Answer:
The temperature associated with this radiation is 0.014K.
Explanation:
If we assume that the astronomical object behaves as a black body, the relation between its <em>wavelength</em> and <em>temperature</em> is given by Wien's displacement law.
where,
λmax is the wavelength at the peak of emission
b is Wien's displacement constant (2.89×10⁻³ m⋅K)
T is the absolute temperature
For a wavelength of 21 cm,
1. B. Liquid
2. C. both A & B
3. C. Indefinite shape and definite volume
4. D. Sublimation
5. Its gotta either be B or D its most likely D
6. A. Neutron
7. D.12
8. C. Ground State
9. C. Synthesis reaction
10. D. None of the above
11. Both A and C
12. A. 2
13. A. Element
14. A. Cu
15. D. Periods, Groups
16. B. Metals, Non-metals
17. A. F
18. D. None of the above
19. Either B or D
20. B. H-2.06% S-32.6% O-65.3%
21. A. Na2SO4
22. C. Combustion reaction
23. if I'm correct it should be C. Nitrogen Bromide
24. Sorry not sure what the answer is but your welcome I hope the rest of theses help!!

There are two types of 'quantities' namely: scalar and vector
A 'vector' is a quantity that has both magnitude and direction whereas a 'scalar' has only magnitude.
Magnitude is a measure or the size of the quantity or object.
In the given example of the vector: '75 mph to the north'
Magnitude is the number 75 mph
Direction is north
Ans C)
